COMBINED FRICTION-TOP AND WAX-SEALED CAN.

Application filed nugust 27, 1919. Serial No. 320,104.

Be it known that I, Josnrn PATRICK WELLS, a citizen ofthe United States, resid- 7 1n and State oflWest Virginia, have invented.

at Wheeling, in the county of Ohio a new and useful Improvement in Combined, Friction-Top and Wax-Sealed Cans,

' of which the following is a specification.

' This invention relates to. improvements in metallic cans of the kindused as containers for various kinds of commodities or for preserving perishable food stuffs.

Cans on which the tops are held by friction, such as are used as containers. for coffee and other materials, can not, as ordinarily made, be used for preserving perishable materials, such as fruits, vegetables, meats, or the like and consequently after a can ofthis kind has been'emptied it is of no further use. It is therefore, desirable to produce a can in which a friction top closure is used and which may be first used in connection with the sale of coffee or. other products and then used for preserving, the cover being adapted to be hermetically sealed by means of wax or other material.

The objects of this invention are to provide a can of this kind with a top which may either be closed ,by friction .whenxthe can is used as a container for goods, such as ooflee, baking powder, or the like, or which .may be hermetically sealed by suitable means, such as wax; also to provide a can of this kind in which the top end and the cover are so formed that the can may bev closed either by friction or by means of a Y Wax or analogous seal, and that the cans may be efiiciently and economically manufactured; also to improve the construction of cans of this'kinol in other respects hereinafterspecified; i i

In the accompanying drawings:

Fig. l is a sectional elevation of a can provided with a can end and co-verembodying the invention.

Fig. 2 'isfragmentary sectional elevation thereof, on an enlarged scale, showing the can closed by means of a wax seal.

Fig. 3 is a fragmentary sectional elevation ofthe cover-detached from the can end.

Fig. dis a fragmentary sectional elevation of a can with the .cover removed.

A represents the can body, which is preferably of, the usual cylindrical form, and.

B represents the usual end or bottom of the can which maybe secured to the body in any suitable manner, solder being employed in the construction shown. A can body and end of any other construction may be employed if desired.

g The can is provided at its upper end with an annular top end portion (hwhich may be secured to the can body in any desired purpose, the top end is provided with an annular inclined portion 0 which extends inwardly and downwardly from the upper part of the flange c, the lower portions of the inclined portion terminating in a wax groove 0 The inner wall of the-wax groove is formed by an upwardly-extending lip or flange 0 having an inner friction'face 0*. The wax groove is comparatively shallow and the angle between the inclined portion 0 and the planeof the top end is preferably less than 45 so that a knife or other sharp tool can be inserted into the groove at an angle at which the wax or other sealing compound can be readily removed from the groove. A top end of other construction may be employed, if desired.

represents the top cover, which, in the construction-shown, includes a body portion d which is preferably substantially flat and which has an upright friction wall or. flange (5' adapted to co-operate with the friction face 0 of the flange 0 cover is p'rovidedwith an outwardly and The top downwardly inclined annular portion d preferably extending at an angle of substantially 45 from the. friction wall at. The lower edge of the inclined portion ri is preferably provided with a lip or outwardly extending part 6Z3 which is adapted to rest on the bottom of the wax groove 0 when the top cover is in its operative position on the can. The lower part. of the inclined portion d and the lip orpart d cooperate with the wax groove in such a manner as to make it possible to form a strong and durablewax seal in the groove the flange (5 and thepositioningofthe'body [Lied and on account of the shallowness oi the groove, the wax can easily be removed "when it is desired to open the can.

As illustrated, the upright frlctlon wall or flange d or the cover is'of greater height than the upwardly extendiiig'col'lar orilip' c of the can end, whereby the flange cl and body portion (Z of the cover extend" into the can below the top end'and below the collar;

seen that when the wax seal .isusedin ad dition to the friction seahthe extra' 'height'of (Z of the cover belowthe top ,end of the can prevents any tendency-that the-lip 'alt'ot the "cover might otherwise have to play or work loose from the sealing wax 'in groove 0 when the contents ofthe can are' shifte'd, as in handling, and impa:ctwltlithe cover" D.

hen the can is used with the friction closure, it is' only necessary topress the top cover on'the top end asshown'in Fig; 1, in order to close the can. The cover can then easily be remov'edeitherby: pulling up wardlyon'the innerface' ofthe' friction wall cl or by prying the cover ofi= hy inserting a knife or other implementurfder the lip (ii in the wax groove. The shallows groove greatly facilitates the removing ofthe cover' 1 in this manner; When the can is used for preservingfruitsand other perishable goods,

the cover is placedon the can in the usual: manner, care being taken that the-lip d rests at the'bottomo'lf the wax groove; Wax 0r other sealing compouiid, in"liquidiormfls" then. poured into the grooveso astoeo'ver' the lip diasshowninFig."2; Thesha'peot the groove and of the cover enables'the'vwaxto contact with afrelatively' largo'amount of surface, looth'on the top eHd and on the seal. The" shallownessof the groove" also from the gro'o'veto opentliec'an, and after chipping out the wax, theco'veri again 1 he pried off as 1 heremhefore described.

VVh'eu the can is used forpreserving'perish-' ahle goods, the coveris held on the 'ca'n lo'oth bythe wax and by-trictio'n, thus causi'hg the cover" to be held 0n th e"can; muchmore securely than whenonly wa'Xis depended upon to hold'the cover in place;

The formation of thetop end and "coveras shown" also imparts strengthand stiffhess to the upper portion of the *can so that-shocks or jars are'not likely to causethe wax seal tobe hrokens This'-formationis also'isu'ch; as to require a comp arativelyl' small "amount ofmaterial, so that-thecans can he eeonoini cally manufactured. By means. of the constructionshown, it isth'ereiforepossible to produce cans which can be used for the two purposes mentioned, and to do so at a cornitively" shallow: annular T groove; one wall 0t which extenclssat an inclination to thezonter portion of thetop:' end a i'd2 theJother'wall otwhichisxprovided with a fi'ictioir faceaorr: its inner side; and azcove'r havingaa body: por tion providedwith 'I an upwardly'r extending annularwall; 1 adapted .to engage with; said friction fa'ce' arid having an annular (part extending downwardly; from? the" ufpzper por-i tion of said upwardly extending walh-at-e an inclination thereto and terminating-1'. in. an
